As you might expect, ecommerce giant Amazon was a big winner.
Traffic to Amazon grew nearly 21% for this year's Black
Friday compared to 2014, according to
ChannelAdvisor. And traffic to eBay grew 1.5% on
Black Friday.

Price comparison tool Google Shopping was another huge winner,
with traffic growth about 40% year over year, ChannelAdvisor
says, while other online stores (which include sites
like Best Buy, Sears, Rakuten.com, and Shopping.com, but excludes
Amazon and eBay) claimed their fair share, collectively seeing
a 77% increase in visitors.

More than half of shoppers — 57% — used their phones and
tablets to browse ecommerce sites. And a large percentage,
35%, made the actual purchase on their phones or tablets,
instead of switching to their PCs to do that, IBM says.

As to what people bought online: Electronics, electronics,
electronics.
